Title: Methods and compositions for genetic therapy and potentiation of anti-tumor immunity
Inventor: FROST PHILIP
IPC: A61K35/12
Filed: 1991-09-12
Abstract: The invention provides a preparation of tumor cell lines containing an exogenous gene encoding a polypeptide that potentiates the immune response to the tumor, for example, interleukin-2. The invention includes methods for cancer therapy by immunization with the immunopotentiating tumor cell.   The invention also provides methodology whereby one can selectively ablate in vitro and in vivo genetically altered cells.  A preferred embodiment of this aspect of the invention includes a cell containing a first exogenous gene encoding an immunopatentiating polypeptide and a second exogenous gene encoding a "lethal" or "suicide" polypepticide, preferably under the control of an inducible promoter.   Introduction of the second exogenous gene confers the ability to selectively kill the tumor cell by inducing a promoter in operative linkage to the gene encoding the lethal polypeptide to initiate transcription of the polypeptide. Diphtheria toxin or the thymidine kinase of Herpes simplex virus are exemplary lethal genes. An exemplary promoter employed is tho 6-16 promoter, which is inducible with low levels of interferon. Methods for using the cells in cancer therapy are also provided:

Title: An apparatus and method for separating particles using a pliable vessel
Inventor: KALAMASZ DALE
IPC: B01L3/00
Filed: 1991-10-18
Abstract: A method and apparatus for separating target particles from a mixture of target and non-target particles. The apparatus includes a vessel (12) having an inlet (28) through which the mixture may be introduced and an outlet (30) through which the fluid may exit, at least a portion of which is pliable; a bed of binding material (24) disposed within the vessel (12), the binding material (24) attracting the target particles such that the target particles may become bound thereto and being porous enough to allow the non-target particles to pass therethrough; and a screen (26) disposed below the binding material (24) for retaining the binding material (24) in place. The pliable portion of the vessel (12) permits the user to separate the target particles from the binding material (24) by merely squeezing the pliable portion in such a manner as to cause relative movement in the binding material, thereby creating the necessary degree of agitation to cause the target particles to become dislodged from the binding material (24). The deformation of the pliable vessel (12) can be accomplished by either the user physically squeezing the vessel (12) with his/her hand or using an external apparatus (32) that applies the necessary force to the vessel (12).

Filed: 1993-04-28
Abstract: Procédé d'amplification d'ARN, comportant les étapes consistant à dénaturer l'ARN par chauffage d'une solution le contenant, synthétiser un premier brin d'ADNc à partir d'une amorce appropriée en présence d'une transcriptase réverse, dénaturer l'hétéroduplex formé, synthétiser le second brin d'ADNc à partir d'une seconde amorce en présence d'ADN polymérase, puis à soumettre l'ADNc obtenu à des cycles d'amplification en nombre suffisant. Grâce à la découverte que certaines transcriptases réverses non réputées thermostables sont capables, lorsqu'elles sont utilisées en quantité suffisante, de résister à un traitement de dénaturation de l'ARN par la chaleur à une température supérieure ou égale à 60°C, et même de pouvoir fonctionner, après ce traitement, à des températures élevées correspondant à des conditions suffisamment discriminantes, ce procédé est caractérisé par le fait que ladite solution d'ARN contient dès le départ, tous les réactifs et solvants nécessaires auxdites étapes et que l'ensemble des étapes est effectué dans un même conteneur sans ajout de réactifs ou de solvants. Il est ainsi possible d'opérer, dans des conditions satisfaisantes, en une seule étape de manipulations, ce qui évite notamment des risques de contamination.    Application notamment au diagnostic des infections bactériennes ou virales, et des désordres génétiques, ainsi qu'au typage cellulaire.

Inventor: MIZUTANI YASUKAZU
IPC: G01K1/14
Filed: 1993-05-03
Abstract: An object of the present invention is to provide a fixing method and assembly of a temperature responsive element capable of detecting variation in temperature of discharge cooling medium of a compressor exactly and rapidly and preventing the compressor from being burned.  A through hole is formed in a cover 6 which covers a path for discharge cooling medium of the compressor.  A plug is fixed to the through hole from the side of the path by a fixing member 13.  In this case, it is sealed airtightly by means of a pecking.  Lead terminal pins penetrating the plug is insulatively fixed in the plug airtightly.  Leads are connected to one end of the lead terminal pins projecting outside and the temperature responsive element is connected to the other ends of the lead terminal pins projecting on the side of the discharge path.  The temperature responsive element is disposed not to come into direct contact with a vessel and the cover of the compressor and is exposed to discharge cooling medium as a whole.   Consequently, the temperature responsive element can detect a temperature of the discharge cooling medium exactly and rapidly without influence of external disturbance such as heat from the outside and a path for suction cooling medium.

Patent CA-2096952-A1 (CA)
Inventor: PRIBNOW RICHARD D
IPC: G06F11/00
Filed: 1991-10-02
Abstract: Maintenance modes of operation of a multiprocessing vector supercomputer system are disclosed. The modes allow diagnostics to run on a failed portion of the system while simultaneously allowing user tasks to run in a degraded performance mode. This is accomplished by assigning a processor or a group of processors to run diagnostics on an assigned portion of memory, while the operating system and user tasks are run in the remaining processors in the remaining portion of memory. In this manner, the diagnostics can isolate the problem without requiring complete shut down of the user task, while at the same time protecting the integrity of the operating system. The result is significantly reduced preventive maintenance down time, more efficient diagnosis of hardware failures, and a corresponding increase in user task run time.
